In the 2019 version of the Unearthed Arcana Alchemist Artificer, the Homunculus's hit points are given as:
Hit Points equal to five times your level in this class + your Intelligence modifier
Is this calculated as
\$(5\times level) + {Int Mod}\$
or
\$5\times (level + {int mod})\$?
Best Answer
(5 × level) + INT mod
Because no parentheses or other mathematical indicators are given in the Hit Points section of the Homunculus stat block,
directly translates to "HP = 5 × [your level in this class] + [your Intelligence modifier]", which in turn means "HP = (5 × [your level in this class]) + [your Intelligence modifier]", because of the order of operations.
